This means consists oi' :i pair of partitions which are substentiuily ii shaped in cross section, mounted one within the other in oppositely disposed relationship. The inner partition is denoted by and has ii Circular shield 2'? secured in aperture formed in the'top thereot, which shield surrounds the ffm 11. in Close proximity to the extremities of the blades thereof. This partition 2G is supported 'by angle iron members as iii-- V(limited et 28 :ind is arranged like an. invert ed L? so that the bottoni thereof is entirel open. The walls of the partition are pre erfibly composed of galvanized steel and extend trensverseiy from side to side of the enclosure l., so that there is little: or no chance for the air current generated by the fan ll to escape from the'partition 26 at any plee-e' except the bottom thereof. lt will be no. that the iower port of the partition 2i) is greater in Width than the diameter of the shieid 2'4", and that the upper part oi 'the partition slopes into the said shield in such ai manner to avoid the formation e right ongle. This is indicated it 29, and the purpose of this i'ormation is to olivi-ete the ,'stenoe of air poel(- ets which would he likely to occur in the of right singular format-ion.

The other, and larger partition, is indicated by 30 and .is of substantially the seme form in cross section as the partition 2G. encompasses the smaller partition 26 and is oppositely disposed with i'espeet'to the hitter so that its e is at the top instead or", larger zirtition 30 is sli Y ie with respect to the pnrtitior 6, so that there is a, greater distance between the wail-s of the two purtitions et 'one side than it the other, the greater distance being shown, at the right in iig. partition 3Q is secured to angle iron supports at bottom, sides :met top, indicated et 31, B2, 33, and its top is almost ievei with the lower face of the fri-n ll, The bottom of the partition moed from. the bottom oi the partition 5i l i stance equal to aboutone seventh (1/7) ot the distance from the lower ffice ot the tim l1. to the bottom of the partition 80.

The partition 30 is composed of thermonel, which is bounded by the partition 30 on 'the one hanfl .und by thel Walls and bottom of the. enclosure l on the other hand.

vertical siifle parts are denoted by 108, 109, and the horizontal bottom part by 110.

Therino-insulating plates lll like the plates 3, are also arranged in trough-like Yfornitransziersely of the enclosure above the fan. '.lhe sloping sides of thistroughlike arrangement serve to guide the returning: air currents to the topio the fan l17 :ind the fact that it is composed of' thermoinsulating; material also prevents the bear" infr l' and motor from h oining too hot. ,in operation`r a suitable amount oi' Steam )lieti to the .ralator 1 35, 3G and 3?? a he 'fan lli. nml chains i lf3, are at tuaef't by their ilri nei innisin. ,The workman standing, opening 1G5- s the plate lill or oi mi' ai fles to i310 ,1 on its inolililO- which latter is rest ii if on a shelf 100 ot' a, t '.l iis opera` tion repeated until all the shelves :ire

the plates are out of Contact with the healed air currents thoughubjectecl to n Somewhat elevated temperature. This is a feature of im` errance, since. it is desirable that the a should not subjected to too great :i heat at this initial stage oii`- their drying operation. pai-:Seil ihosproijl/et 43. and are descending between the partitions 2G and 3l), they come in Contact with an ascending current oi"l hea :rl air, but this current is not as hot as 'i'.iat which is to be f xrie .iiinm'efl ata. later stain? of trayeh owing to t" location of tho 'i itoiis. l

T he perforatione 102 in the shelves 100 permit the access of a certain amount of heated current to the under-si le of the molds and thus suitably' Warm them simultaneously with t e heating and drying of the plates. The :tact that the trays with This channel is substantially U shaped and its W the sprocket lf-l, it will be` jitter the pla-tes have die JEL.

denoted in this cese 'by 114i-, and extends entirely across the endlinachine. Angle bars, one oit which is denoted by 115, project at each side of the enclosure 1, at the height ot 'the feed opening; 'lle and carry et their ends bearings, one of which is marked 116, in which is ,mounted a 'shaft 117, upon which is fixed a pair ot sprockets, one ot which is shown inv Fig; 10 and marked 118. The chains, one of wl. i is shown and marked 112, around the sprockets 112, 113, 118, and their mates, with the result that the courseo'f the trays carrying the articles to be dried includes a section which is exterior 'to the enclosure.

This arrangement is particularly desirehle in case the apparatus is used as a niangle, that is, for drying the articles after they have been dipped in thel glaze. The

'glaze tub is conventionally represented at 120, and it will be seen that the operator can dip the articles in the glace and then place them upon the trays as the latter pass around the sprocketlll without having to reach into the machine. rihis is a greet advantage when two tubs of glaze are being used. Furthermore, this permits the glaze to drip from the articles immediately after they have been placed on the trays, back into the tub 120, instead of down o' o 'the articles on the succeeding tray, because at the time each tray is loaded it stands out beyond the succeeding; ti' `id. over tl e' tub 120, as inrenie iclt in 10.

in, l also prefer to4 use a modified traywliith consists of a pair of similar brackets 121 that are hung on the pins 9? which project from the chains described in connection with the preferred forni.

Each o these trays has one shel't' 122 which is composed c't a series ot slats. 'The central slats have sets ot pins 1225 upstandiiig troni .one side thereof so that shallow dishes, such es plates, may be stood on edge, as ii1dicated in dotted lines.. This attitude oi, the plates, in connection with the slotted or perforated structure of the shelf 122, permits the drying air current to have tree eccess to all surfaces of the plates, and only requires thel plates to have small surface contact with the shelf. 'lfhis is particularly advantageous` in connection with a lat article, since if it were set flat on theshelt 122, the latter would cover a considerable portion oit' its surface. The slielt. 122 engages the brackets 121 by means of trunnions 124 which are fitted totravel in slots formed in the brackets 121; and the said brackets are bifurcated and bent at right l angles at their lower parts so as to provide e, resting place :tor the ends of the shelf 122. rhis construction enables the shelves 122 to be reversed, .which is accomplished by lifting the shelf upwardly with respect to the breckets 121 until is at a snlcient height reeaeei A above the lower part olE the said brackets so that it may bc rotated on its truiinions 1211 without engaging the lower part ol the bracket. lVlien at this height the shell may be turned over and permitted to slide down l' again onto the lower part oit the brackets. rllie two positions o1 the shelic 'are clearly shown in F' 133 and 1st, and the halt-way position is represented iii dotted lines, Fig. 12. Then the shelf has been reversed to the position shown in Fie'. 14, it presents a smooth or ribbed sui-tace upon which relatively high articles suoli as cups (shown in dotted. lines, Fig. 14) may be placed, alter they have been dipped in the glaze, and satisfactorily dried; the apertures between the slats which compose the shelf permitting ready access of the drying-air to articles ot this character.

Referring to the iiiodilied torni shown Iin Fig. 15, it may be said that 'this is in principle substantially like the preferred forni shown in 1 to i?) inclusive. r There are, however, seine 'points to which attention may be directed.

'lne enclosure, which is denoted by 12,5 is

intended to be of the saine construction as the preferred torni. The inner partition, which corresponds tov and is 'ot the same construction as the partition 2t), is marked 126 and consists of a pair .of members which project downwardly from the top ot the enf;` closure for a relatively short distance. The outer partition 127, which corresponds to and is of the saine construction as .he partition 230, has square corners and is hung,` freni the supports for the shafts that carryzthe four end sprockets iii the upper rows. Anl` additional single partition 126`rz is placed in the` centre of' the enclosure and spaced .troni the bottom of the partition 127 and the top of the enclosure.

llhe sprockets are denoted by 128, 129, 130, nu, 132, isz-i, isi, 135, ist, is? and .1:58, and

it will be noted that there are live sprockets l in the upper row and tour sprockets in the lower row within the partition 127. The
